Is this a new feature? I got a notice at the beginning of my turn that I had researched masonry....yet I was in the middle of researching Mathematics which is still 7 turns away. Masonry was way back in the tree - I had skipped a lot of the early techs. Does building mines or something else eventually give you masonry anyway? Or is this a bug...TIA for any insights.
